At Spherix® Mineral Products, we manufacture aluminosilicate ceramic spheres that have been developed from a 100% recycled material stream. Our products are derived from pond remediation sites that have coal slurry in them. Our company, The SEFA Group, mines the ponds which creates an immediate positive environmental benefit. We use that raw material as a value add product through our patented STAR® process and manufacture it for the plastics and rubber markets after specific treatments are custom engineered and bonded to its surface.
